1. A condensate trap comprising:
a back portion comprising a first passage enclosed between a first wall and a second wall, the back portion further comprising:
a first opening connecting the first wall and the second wall;
a first float placed over the first opening such that the first float does not travel below the first opening; and
a first constriction above the first opening such that the float does not leave the first passage; and
a front portion comprising a second passage enclosed between a third wall and a fourth wall, the front portion further comprising:
a second opening connecting the third wall and the fourth wall;
a second float placed below the second opening such that the second float does not travel through the second opening; and
a second constriction below the second opening such that the second float does fall below a predetermined level;
wherein when there is a positive pressure in the condensate trap, and there is no condensate collected in the first passage, the first float is pushed by the positive pressure in the first opening.
